NOL6

Chr 9

nucleolar protein 6

The NOL6 protein is a nucleolar RNA-associated protein that participates in ribosome biogenesis as part of the small subunit processome, working to process nascent pre-rRNA through folding, modifications, and cleavage. Mutations cause autosomal recessive neurodevelopmental disorder with microcephaly, epilepsy, and brain atrophy. This gene is highly constrained against loss-of-function mutations, indicating its critical importance for normal cellular function.

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
